Abstract EN
The penetration grouting is very widely used in geotechnical engineering nowadays, but the slurry diffusion radius is not long enough because of low grouting pressure.
The vacuum grouting method is proposed to solve this problem.
However, there is no diffusion theory model of vacuum grouting, which makes the practical application lack scientific basis.
In this paper, the distribution law of vacuum negative pressure in soil is deduced.
Then, the boundary conditions of Maag’s spherical diffusion model are modified by the vacuum pressure distribution law.
After that, the vacuum modification model is deduced.
Finally, Maag’s model and modified model are analyzed according to a published experiment, which proves that the vacuum modification model is suitable for predicting the slurry diffusion of vacuum grouting.
The proposed model provides a reference for the theoretical study of vacuum grouting.
